What the problem with the machine, at least I believe, is, is that the
memory is not getting any power.
The light on the H745 is not coming on. I'm trying to figure out why.
OK, let's start there. Make sure the bulb isn't blown. It happens, all
too often.
Then check the AC input to that brick. Connect an AC voltmeter between
the 2 wires that come from the transformer (the ones labelled '20-30V
AC'. What do you read there?
Then connect a DC voltmeter between the 0V connection (or system ground)
and each of the output terminals in turn. What voltages do you read there?
